 Original concept had 4 sub-pixels, so had lower resolution and more
data lines vs. a conventional display
 We now combine RGB1B2 concept with our BYcolor patterning to
produce the best of both worlds…

 Deposit 4 sub-pixels at
a time through each
mask opening
 Mask is now only ½ the
display resolution (in
both x and y directions)

 FMM EML mask can deposit 4 pixels at the
same time
 Can apply sub-pixel rendering to reduce
sub-pixel density
 We estimate this approach can lead to
>1,500 dpi OLED displays
 Improved lifetime over current display
